Just a quick post, here are the commands I ran to get RVM working on my new Macbook:

sudo mkdir /usr/local/lib
sudo bash < <( curl -L http://bit.ly/rvm-install-system-wide )
sudo dseditgroup -o edit -a YOURUSERNAME -t user rvm
echo '[[ -s "/usr/local/lib/rvm" ]] && . "/usr/local/lib/rvm"' >> ~/.bash_profile
source ~/.bash_profile
rvm install 1.9.2
rvm --default use 1.9.2
rvm 1.9.2
ruby --version

If you recently upgraded to Emacs 23 from Carbon Emacs on your Mac you might have found all the control keys are bound wrong. Anyway it’s easy to fix, add these lines to your .emacs and restart Emacs.

; Setup the Mac keys
(setq mac-option-key-is-meta nil)
(setq mac-command-key-is-meta t)
(setq mac-option-modifier nil)
(setq mac-command-modifier 'meta)
(global-set-key (kbd "<kp-delete>") 'delete-char)

I was having a problem on my macbook that I had to login every time I wanted to save or open a new file through Tramp. The weird thing was that tab completion only required me to login once.

Anyway I got to the bottom of it, just add this to your .emacs:

(setq tramp-default-method "ssh")

If you are having problem getting the darwinport of meld running on your mac try these two commands before running the program again.

sudo launchctl load -w /Library/LaunchDaemons/org.freedesktop.dbus-system.plist
sudo launchctl load -w /Library/LaunchAgents/org.freedesktop.dbus-session.plist

The error I was getting before was this:

Xlib: extension "RANDR" missing on display "/tmp/launch-RsRIqw/:0".
